LASFIT TK1 Tire Inflator Portable Air Compressor, Cordless Tire Air Pump for Pickup Truck, SUVs, Heavy-Duty Car Air Pump with Larger 12000mAh Battery, 150PSI Digital Pressure Gauge, Smart Auto Stop

I purchased one of the TK1 inflators for myself in august 2024 and just purchased another one as a gift in Christmas 2025. I'm really happy with the power, inflation speed, convenience, and accuracy. My family has four drivers, so inevitably somebody always seems to need to level up their tire pressure. This inflator is great for this situation and is much more convenient and faster than dragging out my compressor/hose. In addition to tires, I've also used it for some bike tires, balls, and kids inflatables and it worked really well. It has settings for each of these which is nice and dummy proof. While it doesn't inflate as fast as a regular air compressor, I think that it inflates tires reasonably fast and I like the auto shutoff and the set inflation amount. I've found the charge to last a long time based on my occasional use. I haven't found a noticeable phantom drain in the battery, even after a couple months sitting on a shelf. After an initial charge when I got it, I topped off numerous cars before charging and it still had a single bar. I don't know if that result is technically 'good' or 'bad', but it exceeded my expectations. I've found it to be pretty accurate compared to my TPMS and tire gauge readings. I do find each tire loses a little air when disconnecting the hose, so I typically overinflate by 1/2 lb and it seems to be perfect. I did notice the 2025 version had an updated hose design. Instead of attaching the hose to the inflator with a push and twist motion, it now screws on. This takes a little more time and is less convenient, but maybe they determined it is more secure. Overall the TK1 is a convenient device that inflates accurately, maintains a good charge, and is small for easy storage. I purchased both of mine on sale. At the sale price it is a good value, but it is overpriced at MSRP.

I love this tire inflator and it comes with us on every single trip—and for good reason. The LASFIT TK1 has handled everything I've thrown at it: bikes, the RV, cars, and the truck, all without breaking a sweat. The 150PSI output has plenty of power for larger tires, and the digital pressure gauge makes it easy to dial in the exact PSI without guessing. The smart auto-stop feature is a great touch—set your target pressure and it shuts off automatically so you never have to worry about overinflating. The 12000mAh battery life is genuinely impressive; at a full charge I can top off both the RV and truck tires in one go without needing to recharge in between, which is exactly what you want when you're out camping or on the road away from a power source. It's compact enough to toss in a bag or storage compartment, and the build quality feels solid and road-worthy. This is one of those tools that once you have it, you wonder how you managed without it. If you're looking for a powerful, reliable, cordless tire inflator that can handle everything from bikes to big truck and RV tires on a single charge, the LASFIT TK1 is an absolute no-brainer.

Inflates standard car tires pretty quickly, and is a good bit quieter than our other cheap no-name battery powered inflator. I've been using it pretty frequently lately to top off mine and my girlfriend's tires, and sometimes completely fill from flat one of my tires, as I've got a leak that I haven't gotten around to fixing yet. It's got a great battery capacity, and could probably fill 3 or 4 standard car tires from flat before the battery goes dead. (The pictures) - Another bonus is that it's tested to be very durable, by me on accident. I was in a rush to leave work before the big snowstorm got too bad, and was so focused on getting home before I got stuck, that I had forgotten that I was filling my tire while my car was warming up, and started to drive off. I didn't make it far (15 feet) before I heard the scraping noises and felt a bump (I sort of ran it over). It surprisingly still works as it did new, however something must've shorted out from the snow and it no longer charges, which is a bummer considering I just upgraded from a much cheaper and worse option. Tl;dr - Fast - Quieter than other options I've used - Large battery capacity - Survives being run over (I do not recommend testing this part)

9/23/26. Unfortunately, now the pressure hose comes loose almost immediately when starting pumping. You need 3 hands: 1 to hold the LASFIT, one to hold the pressure hose from turning inside the LASFIT connection, and 1 to screw the pressure hose to the air valve. Almost impossible. 11/6/2025: Lasfit recently pumped 2 completely flat tires, different cars, to Full 30lbs enough to get to repair station. Review below is still accurate. But I noticed air hose connection at the Lasfit Device, has popped out several times. A "solid" connection is not readily apparent. Turn hose in the device 90deg, 180deg, or what? You have to quickly remove hose from the tire, or the air you just pumped in leaks out. Then hook it all up and start again. 1/10/25. EARLY REVIEW: Bought this LASFIT LAP-TK1 mid-Aug 2024, charged it, put it in my trunk. First time use since then, 5 months later, filled 4 low tires on my Accord. It's been bitterly cold this December and January, and I hadn't checked my tires since summer (yeah, me bad boy). And I had put off the checking and filling until this 40F day. The Lasfit is relatively expensive compared to my last inflator (last one was a different brand, 4x cheaper, much slower, hard to fasten to valve stem, and circuit breaker often tripped due to heat/working too long - finally quit on me), but this LASFIT is definitely well worth the peace of mind it gives me. Pumped fast without tripping out. Am now recharging it from 3/4 to 4/4 level at home with the USB cord and my charger. It screws onto my valve stems without cross-threading any threads, male or female. It's a bit noisy, but pumps quickly to the set point. As I remove the air hose from the valve stem, pressure does not leak from the tire, and my pressure gauge shows pressure identical to my set pressure. I added 8 lbs. to each of 3 tires, and 18 lbs. to the 4th.

I recently had the pleasure of using a cordless tire inflator that completely changed my perspective on the convenience and efficiency of maintaining proper tire pressure. This device, with its impressive large battery, has redefined what I expect from portable inflators. On a single full charge, I was able to inflate my Cooper ST MAXXX tires from 30 PSI to 35 PSI in under three minutes - and the battery indicator still showed full! This performance alone speaks volumes about the battery's capacity and the inflator's efficiency. One of the standout features of this inflator is its sturdiness. It's built to last, which is exactly what you want in a tool that you'll be relying on in various situations. Additionally, it comes with a practical carrying case, making it easy to transport and store. The designers have thoughtfully included a convenient storage area for attachments, ensuring that everything you need is organized and within reach. Using the inflator is as straightforward as it gets, thanks to the quick attachment feature. It connects seamlessly to the tire valve, but a pro tip here is to ensure it's inserted all the way for an optimal seal. This small step guarantees that the inflation process is not only quick but also hassle-free. Overall, I am thoroughly impressed with this cordless tire inflator. Its combination of a long-lasting battery, robust construction, thoughtful design, and ease of use makes it an indispensable tool for anyone looking to maintain their vehicle's tire pressure efficiently. Whether you're an avid off-roader or someone who appreciates the peace of mind that comes with having reliable tools, this inflator will meet and exceed your expectations. I highly recommend it to anyone in the market for a tire inflator that can handle everything thrown at it.

Have had this for a year and the battery and the power have not been affected. By far the best small compressor I have and I have 4. This compressor take from 0-35psi in minutes not a hour but 2-3 minutes! Buy this one with confidence

I love the compact size and it’s light enough for me to easily carry. It’s easy to charge and store in the car; I have had more than one occasion when having this on hand would have been extremely useful so I would recommend it as a gift, especially to a young person who is becoming independent. A single charge on the device is enough to inflate all 4 tires. It is fast and easy to use. There are two drawbacks: it’s very noisy and the gauge differed considerably from my car’s internal pressure sensor. Because of its portability and because I know what it’s like to be in the middle of nowhere with tire pressure problems, this is well worth the expense.

If you’re trying to decide between this pump and the hundreds of similar-looking battery-powered inflators out there, stop here. After watching several teardown videos, it’s clear that many other brands aren’t what they claim to be - their components and batteries are misrepresented in their listing. After watching the teardown of this Lasfit pump, it was one of the only products that was well-built with good engineering. I had bought a different inflator from a different brand (LOLSSA), charged it up, tested it once, tossed it in my car, and when I actually needed it on the road, it failed. That experience made me realize there is no point in putting one of these in your vehicle unless you get one that is reliable. To me, what separates a compact inflator like this from a traditional compressor (like a Viair) is the convenience and speed of use. I work in an industrial area and end up with five or six slow leaks a year from nails or screws. In Portland’s dark, rainy weather, the last thing I want to do is pop the hood, unwind wires, and hook everything up just to top off a tire that’s down 10 PSI. With this pump, it’s quick, easy, and safe. There are videos of people inflating truck tires with this unit - and while it's not its intended use, it shows you what it's capable of and gives me confidence that it will reliably handle what I need it to do. I had a minor issue with what came in the package, and Lasfit’s customer service was excellent. I spoke to a real person who genuinely cared about making things right. The carrying case is fantastic. It's harshelled and zippered and keeps all the components together. The LOLSSA brand came with a fabric bag that allowed the pieces to spill out. Lasfit isn't skimping on what they're including for the price. Overall, this is a well-engineered, high-quality product backed by an honest company that stands by its customers. That's rare. I'll give them my money. Great experience all around.

MUY RAPIDO Y EFICIENTE AUN CON CARGA NAJA
